has been walking
walked
would have walked
相似考题
参考答案和解析
句意：在步行半个小时后，她意识到她在此之前走错方向了。这里主要考查动词的时态。根据realized可知她走错是在realized之前，因此是过去的过去，要用过去完成时，又因直到她realized的时候她仍然在继续向前走，因此要用过去完成进行时态。过去完成进行时表示某个过去正在进行的动作或状态，持续到过去某个时刻还未完成，一直持续到当前才结束。

第5题：
DOn May 23,1989, Stefania Follini came out from a cave at Carlsbad, New Mexico. She hadn’t seen the sun for eighteen and a half weeks. Stefania was in a research program, and the scientists in the program were studying body rhythms(节奏). In this experiment Stefania had spent 130 days in a cave, 30 feet in depth.
During her time in the cave, Stefania had been completely alone except for two white mice. Her living place had been very comfortable, but there had been nothing to tell her the time. She’d had no clocks or watches, no television or radio. There had been no natural light and the temperature had always been kept at 21℃.
The results were very interesting. Stefania had been in the cave for over four months, but she thought she had been there for only two. Her body clock had changed. She hadn’t kept to a 24-hour day, she had stayed awake for 20-25 hours and then had slept for 10 hours. She had eaten fewer meals and had lost 171bs in weight as a results! She had also become rather depressed（抑郁）.
How had she spent her time in the cave? As part of the experiment she’d done some physical and mental tests. She’d recorded her daily activities and the results of the tests on a computer. This computer had been specially programmed for the project. Whenever she was free, she’d played cards, read books and listened to music. She’d also learned French from tapes.
The experiment showed that our body clocks are affected by light and temperature. For example, the pattern of day and night makes us wake up and go to sleep. However, people are affected in different ways. Some people wake up naturally at 5:00 am, but others don’t start to wake up till 9:00 or 10:00 am. This affects the whole daily rhythm. As a result, the early risers, on the other hand, are tired during the day and only come to life in the afternoon or evening!
第68题：
Stefania stayed in the cave for a long time because ______.
A. she was asked to do research on mice
B. she wanted to experience loneliness
C. she was the subject of a study
D. she needed to record her life

Bhasn’t she
Cwouldn’t she
Ddidn’t she
正确答案： B解析：
虚拟语气及反义疑问句题。一般来说，反义疑问句要与主句的主语和谓语相对应，主句的谓语部分为would have been…，主语为Laura，在反义疑问句中用she指代，所以本题应选C。 -

A had
B had had
C would have had
D has had
正确答案：A选［A］。本题重点考查动词的时态。句子的主句用的是一般过去时(felt)，由when状语从句的时态(过去完成时)可以判断出as后面的从句的时态也应该用过去完成时，即had felt。为避免重复，felt可以省略。 -
第18题：

第19题：
